OBJECTIVE: To explore the methods, fixation points, and effectiveness of staged therapy using external fixation frame in treatment of infectious nonunion near knee joint. METHODS: A retrospective analysis was conducted on the clinical data of 60 patients with infectious nonunion near knee joint, who underwent staged therapy using external fixation frame between June 2021 and June 2024 and were followed up. There were 48 males and 12 females with an average age of 47.9 years (range, 16-70 years). The disease duration ranged from 9 months to 20 years, with a median of 14 months. Among them, 21 cases of infectious nonunion located in the distal femur, 36 cases in the proximal tibia, and 3 cases in the patella; 12 cases exhibited segmental bone defects (≥4 cm), while 48 cases presented with localized bone defects (<4 cm). Osteomyelitis was classified using the Cierny-Mader system, with 3 cases classified as type Ⅰ, 6 cases as type Ⅱ, 35 cases as type Ⅲ, and 16 cases as type Ⅳ. Preoperative C-reactive protein levels ranged from 15.1 to 55.8 mg/L (mean, 36.4 mg/L). The erythrocyte sedimentation rate was 35-80 mm/1 h (mean, 56.9 mm/1 h). The Hospital for Special Surgery (HSS) score for knee joint was 69.3±17.7 and the range of motion was (70.61±40.60)°. After debridement and placement of antibiotic carriers at the first-stage operation, unilateral orbital frames ( n=14), combined frames ( n=27), or Ilizarov frames ( n=19) were used for cross joint fixation ( n=9) or joint preservation fixation ( n=51). After 6-8 weeks of infection control, the bone grafting or bone transport was performed at the second-stage operation based on the type of bone defect, with internal fixation employed as an adjunct if necessary. After operation, the infection control and fracture healing were observed and the bone healing time was recorded. The knee joint function was assessed using the HSS score, and the knee joint range of motion was measured as well as the angle of motion loss. Patients were grouped according to the site of nonunion, type of external fixation frame, and fixation method. The bone healing time, change value of HSS score, and knee joint range of motion loss (difference between pre- and post-operation) were compared between groups. RESULTS: All infection markers returned to the normal range within 6 weeks after the first-stage operation. All patients were followed up 12-48 months (mean, 22.0 months) after the second-stage operation. There were 5 cases of needle tract infection during the external fixation period, and 3 cases of infection recurrence after the second-stage operation, all of which were cured after symptomatic treatment. The bone healing time was 6-18 months (mean, 11.0 months). At last follow-up, the HSS score was 88.5±7.9 and the range of motion was (61.84±40.59)°, with significant differences compared to preoperative values ( P<0.05); the knee joint range of motion loss was (8.77±11.07)°. The bone healing time was significantly longer in the distal femur group than in the proximal tibia group ( P<0.05), and in the unilateral orbital frames group than in the Ilizarov frames group and the combined frames group ( P<0.05). The angle of motion loss was significantly larger in the Ilizarov frames group than in the unilateral orbital frames group and the combined frames group ( P<0.05). The change value of HSS score was significantly higher in the cross joint fixation group than in the joint preservation fixation group ( P<0.05). CONCLUSION During the first-stage operation, debridement is performed and antibiotic carriers are placed to control infection. External fixation frames are then precisely positioned based on the distance between the lesion and the joint surface, avoiding the infected wound while ensuring mechanical balance. During the second-stage operation, bone grafting options are selected according to the extent of bone defects to enhance the bone union. Postoperative early functional exercises of the knee joint are permitted to improve joint function.

OBJECTIVE: To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. METHODS: Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. RESULTS: All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. CONCLUSION Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.

Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

Objective: To compare the effectiveness of blonanserin and olanzapine in the treatment of first-episode schizophrenia, so as to provide the basis for the medication choice for the treatment of first-episode schizophrenia. Methods: A total of 98 patients with first-episode schizophrenia admitted to the Second People's Hospital of Taizhou City were selected and randomly divided into the olanzapine group and the blonanserin group for a treatment period of two months. The Positive and Negative Syndrome Scale (PANSS), Pittsburgh Sleep Quality Index (PSQI), MATRICS Consensus Cognitive Battery (MCCB) were used to investigate the improvement of symptoms, sleep quality and cognitive function before and after treatment, respectively, and the level of prolactin was detected. The generalized estimation equation was used to compare the differences between the two groups. The adverse reactions of the two groups were recorded and the safety of medication was evaluated. Results: Forty-nine patients each group were included, with 29 males and a mean age of (37.22±7.17) years in the olanzapine group, and 27 males and a mean age of (37.54±7.31) years in the blonanserin group. There were no significant differences in gender, age, disease course and educational duration between the two groups (all P>0.05). The scores of positive symptom, negative symptom, general psychopathology and overall PANSS in the two groups after treatment were decreased compared with those before (all P<0.05). However, there was no significant difference between the two groups, and no interaction between the drugs and treatment duration (all P>0.05). The MCCB score of the blonanserin group was higher than that of the olanzapine group, while the PSQI score and the prolactin level of the blonanserin group were lower than that of the olanzapine group, and there was an interaction between the drugs and treatment duration (all P<0.05). The incidence of adverse reactions in the blonanserin group was 6.12%, which was lower than that in the olanzapine group of 20.41% (P<0.05). Conclusion Either blonanserin or olanzapine can improve psychotic symptoms inpatients with first-episode schizophrenia, while blonanserin is more effective than olanzapine in improving sleep quality, cognitive function and reducing prolactin level, and has higher safety.
